<p><i>tiffgt</i> displays one or more images stored using
the Tag Image File Format, Revision 6.0. Each image is
placed in a fixed size window that the user must position on
the display (unless configured otherwise through X
defaults). If the display has fewer than 24 bitplanes, or if
the image does not warrant full color, then
<small>RGB</small> color values are mapped to the closest
values that exist in the colormap (this is done using the
<i>rgbi</i> routine found in the graphics utility library
<b>&minus;lgutil</b>.)</p>

<p>Data may be organized as strips or tiles and may be
compressed with any of the compression algorithms supported
by the <i>libtiff</i>(3) library.</p>
<!-- INDENTATION -->
<p>For palette images (<i>PhotometricInterpretation</i>=3),
<i>tiffgt</i> inspects the colormap values and assumes
either 16-bit or 8-bit values according to the maximum
value. That is, if no colormap entry greater than 255 is
found, <i>tiffgt</i> assumes the colormap has only 8-bit
values; otherwise it assumes 16-bit values. This inspection
is done to handle old images written by previous (incorrect)
versions of <i>libtiff</i>.</p>
<!-- INDENTATION -->
<p><i>tiffgt</i> can be used to display multiple images
one-at-a-time. The left mouse button switches the display to
the first image in the <i>next</i> file in the list of files
specified on the command line. The right mouse button
switches to the first image in the <i>previous</i> file in
the list. The middle mouse button causes the first image in
the first file specified on the command line to be
displayed. In addition the following keyboard commands are
recognized:</p>
